THE VEGETATION OF THE DISTRICTS OF 
khuri. But apparently now-a-days the name khasi is applied to both 
the forms of S. spontaneum , and so far as I can ascertain the name 
khuri, without any qualifying epithet, is restricted to S . fuscum . 
640. Pollinia Trin. 
* Pollinia argentea Trin.; B. P. ii. 1190. Andropogon trispicatus 
H. S. 707 . 
In new pasture land, occasional. 
Pollinia conjugata. Andropogon conjugatus H. S. 707. 
Serampore, according to Voigt. 
This record is doubtful but deserves to be looked into. The 
grass in question, described by Roxburgh as Andropogon conjugatus , 
is stated by its author to be a native of Bengal, though no precise 
locality in Bengal is cited. He has left a coloured drawing of the 
species, but there is not now in Herb. Calcutta, — and the same is 
apparently true as regards Herb. Kew, — any specimen that agrees 
exactly with this figure which is clearly that of an species of Pollinia . 
Hackel suggests that the grass must be very closely allied to P. fim- 
hriata , but it is clearly not that species as Hooker has shown, nor 
from the known distribution of P . jimbriata is it likely to be a 
form of it. There are examples of P . articulata) in Herb. Calcutta, 
that closely resemble in externals Roxburgh’s figure of Andropogon 
conjugatus , but the awnless condition of the second glume of the 
sessile spikelets, as shown in Roxburgh's analysis, precludes the 
possibility of his species being referred to P . articulata , apart 
from the fact that P. articulata , though very common elsewhere in 
Bengal, does not seem to have ever been met with in our area. It 
is not impossible that Andropogon conjugatus may be a correspond- 
ing reduced state of Pollinia argentea , but so far no examples of 
that species, which was, moreover, well known to Roxburgh, have 
been communicated to Herb. Calcutta, bearing the necessary super- 
ficial resemblance to his drawing of Andropogon conjugatus . 
641 . Manisuris Sw. 
* Manisuris granularis Linn. f. ; B. P. ii. 1191. Peltophorus granu~ 
laris H. S. 709 . 
Rather rare in dry meadows west of the river Hughli ; not 
recorded from our area by Voigt and perhaps only a casual with us. 
643. Rottboellia Linn. f. 
* Rottboeliia compressa Linn. f. ; B. P. ii. 1192. R. glabra H. S. 
709.
